Mustafar yep agreed an infiltration mission to block Vaders attempts in the comics that fail, Taboo before that searching for clues in to Anakins relationship with Padme and how that can be turned against Vader, heck even Yavin 4 and Cal being the reason why it's used as a base. But Mortis is being dealt with in Ahsoka, Endor serves no purpose as until the death star was destroyed 1st time around there wasn't a point to it. Bespin unless your gonna go down to the land and have him find Lukes hand....

Nar Shadda though huge amount of gameplay to be had there.
